Worked well to seal silverback vapor barrier to crawl space walls. I did find that the caulk was more difficult to tool than most caulks that I have used. The cure time is relatively long but this dies have the advantage of longer working time. The cured caulk is very soft and flexible. The caulking will stay where you put it. It does not slump.
